I never used Boeshield but TopCote doesn't get sticky, ever. You spray it on and it dries in seconds, then you can wipe it off or not. I wipe it off my big iron, but on vice screws, pipe clamp screws and so on I just spray it on, no wiping.
Long ago, when I first set up my shop in a wet basement, fighting rust was a constant battle. I tried everything, including dissolving wax in lacquer thinner and painting it on my big iron. I good friend of mine worked for 3M and he said he saw some stuff at the 3M company store in Minnesota that might work. He brought me back several cans and it was like a miracle. Couldn't believe everyone didn't use it. I never found it on sale anywhere. I even contacted someone at 3M and he never heard of it., and eventually, when I ran out, I found TopCote. The cans looked strikingly similar however, and I suspect they are pretty much the same stuff. Here's some photo's of the two:
